Acid

Gives away H+

Base

Receives H+ from acid

Properties of acid

pH less than 7, Sour, High H+

Properties of base

pH higher than 7, Bitter, Low H+

pH importance

it is important because it measures the H+ in a solution, which tells us if its acidic, basic or neutral

How indicators work

They change colour, depending on the amount of pH in a solution

n = m/M

number of moles = mass/Molar mass

n = cV

number of moles = concentration × volume

To find the concentration of an unknown

Burette

holds standard solution, and known concentration

Aliquot

Holds unkown concentration

pipette

how to look at exact volume

concordant is in the range of 0.1ml
